Ll'FE-SAVlNG BUOY-BOAT.

SPECIFICATION forming part of Letters Patent No. 385,961, dated July 10, 1388,

Application filed October 13, 1887. Serial No. 252.257. (No model.)

To @ZZ whom it may concern:

Be it known thatl I, JAMES SAMPLE, a'subject of the Queen of Great Britain, residing at l2 Harrison Place, J esmond, N eweastleon- Tyne, in the county of Northumberland, England, have invented certain new and useful Improvements in LifeSaving Buoy-Boats for Ships7 Use, of which the following is a speciication, reference being had therein to the accompanying drawings.

My invention consists in the construction of a life buoy-boat for saving life at sea, which is formed in such a manner that it retains its stability in the roughest sea and cannot founder by reason of waterlogging, and, while being of sufficient capacity for holding several persons, thespace occupied by it on board ship is comparatively small and the opera, tion oflaunching easily performed.

The lower part of the hull of the boat, according to my invention, is preferably hemispherical in form, and is constructed of thin steel or iron plate, either pressed or built up of alternate plates riveted or otherwise attached together to form water-tight joints.

By reference to the accompanying drawings, Figure l represents a sectional elevation, and Fig. 2 aplan, of a life buoy-boat constructed according to my invention.

The lower part of the hull A is shown' as an entire plate, with a deck of metal plate, B,

riveted or otherwise secured to the upper edges of said hull A. Said deck B is pierced with a number of circular holes, into each of which is tted a metal tube, C, of suiiiciently large diameter to permit an ordinary person to stand within it with ease, and of such depth as to allow said person to have the waist level with the deck B. A central orifice is tted with a similar tube, D, of larger dimensions, which communicates with the interior of the hemispherical hull A. A plate, E, is secured to the hull-plate, and also to the lower ends of the tubes-C and D, by riveting or equivalent means. A perforated cap or cover, F, is fitted to said tube D, which serves the purpose of a store-room, wherein food and necessaries may be kept for supporting life when adrift at sea. A water-tight cover may be tted to the cap F, to keep said stores dry when the seais so serving to strengthen the hull of the boat without impairing its elasticity or unduly adding to the weight. The tubes() areconnected by tubes b close to thelower edge, where they 6o are secured to the plate E, so that any water collecting therein may be removed Vby-means vofa small hand-pump placed in one of said tubes C or connected with one of the pipes between the tubes C. A hand-rail, I, is attached to the rim formed by the junction of the deck B with the hull A, and life-lines cl are suspended from suitable ring-bolts. Similar rings are provided for the purpose of attaching slings for maintaining the life buoy-boat in a vertical position on deck.

It will be apparent that the watertight airspace J J wi? prevent the boat from sinking, even though the tube D and thespace below it in the interior of the hemispherical hull forming the store-room be iilled with water by any accident Thewhole apparatus may be placed upon the deck of-a sea-going vessel upon ordinary boat-ehocks and secured by slings from roll- 8o ing out of position. Being extremely light in comparison with its capacity for stowage and displacement, the operation of launching the life buoy-boat is easily and quickly accomplished in cases of great emergency. As an auxiliary equpment,l may provide a sail,oars, anda masty which may be detachable in two or more parts, so that they may be stowed in the tubular' store-room D. These accessories will enable the persons on board the life buoy- 9o boat to keep said boat in the track of vessels.

Tofurthe.` aid the Steerage and manipulation of said boat,I may provide a keel and rudder, which, however, may also be detachable into separate parts, and form no portion of the actual hull.

Having fully described my invention, what l desire to claim and secure by Letters Patent 1s- 1. A metalliclifesaving buoy-boat consisting roo Iron rod stays 55 of an approximately semispherical hull, A, water-tight upper deck, B, having a series of circular openings, water-tight mean deck, E, having a central opening, a central cylindrical tube, l), secured watertight to the edge of the opening of the mean deck E, provided with a cap and a water-tight cover, F, a series of smaller tubes, C, disposed circularly around the central tube and standing upon and secured water-tight to the mean deck, and open at the top and secured water-tight to the up per deck, a anged ring, G, secured to the hull, a flanged ring, H, secured to the exterior of the cylinder D, stays a, connected to said flanged rings, anda railing, I, at the edge of lhenlain deck, substantially as set forth.

2. The combination, in a metallic life saving buoy-boat, of the hull A, main deck B, having circular openings for the reception of tubes, a mean deck, E, having a large circular opening, a central cylinder, D, secured at its lower edge water-tight to thc edge of the opening in the mean deck and at its upper edge tothe main deck, a series of tubes or cylinders, @standing upon and secured water-tight to the mean deck E, and their upper edges secured water-tight to the edges of the openings in the upper deck, a flanged ring, G, secured internally to the hull, a flanged ring', H, sccured externally to the central cylinder, D, stay-rods a, passing between the tubes or cylinders C, having their ends secured to the flanged rings G and H, and arailing, I, secured upon the upper deck, substantially as set forth.

In a metallic life-saving buoy-boat, the combination ofa series of tubes or cylinders, C, open at the top and secured watertight at their upper edge to the edges of openings in the upper deck, and their bottom secured water-tight to the mean deck, and the tubes b, connecting adjacent cylinders near their bottoms with one another, so as to form a communication, substantially as set forth.

In testimony whereof l alix my signature in the presence of two witnesses.

JAMES SAMPLE.
